Experiments for cryopreservation of ram’s sperm, received in non-reproductive season (April-May) have been conducted. There are to observe some differences regarding the biological indexes of the sperm. The same are to explain with the influence of the ecological factors – temperature, continuance of the luminous day, relatively humidity. The ejaculats, got in non-reproductive season are characterized with non significant reduced cryoresistance of the spermatozoa. That is a base for successful cryopreservation of sheep‘s genetic material out of reproductive season.
